Yeah, yeah, I'm sorry I've been negelecting you my lovely reader. There's just a whole lot to play with at the moment, just got a reasonably priced Video Camera, my lovely bike, been playing with VS.NET 2005 Beta 1, getting a new deployment (and tracking down a deadlock) on this site and finally playing with Adobe Premiere Pro - which is just awesome, if you've been stuck with Windows Movie Maker, try a real editing package!
Whew...as well as that I've been looking into SQL Hierarchies using something called 'Nested Sets' by Joe Celko - this really is the best way I've seen of doing hierarchies (well, trees) in SQL. Also ordered his book on the subject Joe Celko's Trees and Hierarchies in SQL for Smarties ...so, with all of that I have to get back to this site. I was very aware that I was just metablogging for a while there which I personally can't stand. So,l no promises but I'll try and get back to things as soon as I can!
UPDATE: Ooh, this is a pretty complex subject and really pretty interesting. There's a couple of other links I can recommend this site has the most complete set of links to the best methods of modelling hiearchical data in T-SQL, this site has a really nice method for supporting Nested Sets in a basically 'automatic' way. There's a whole lot to learn about this topic (much of which is mentioned in the book I mentioned earlier) and articles like this on the 'Nested Interval' model look really useful but will take a bit of work to figure out. Luckily the system I'm developing is fairly loosely coupled in it's Schema, allowing me to easily upgrade the hierarchical model I use if necessary...
